"Playing Idi Amin shifted something inside of me a little bit. It was something I'd been working on for a long time -- trying to understand my heritage. I'd been going back through my family tree as far as I could go -- five generations on each side. Before that, I had to cross over the water to Africa. I even had my DNA tested, because I think it's important to have a sense of your source, a sense of where you come from."
